Tempisque River in Guanacaste

Pretty cool view of some of the shell bank on the Tempisque river, on the other side of the river you can see the Palo Verde National Park. In this photo the banks next to the river are actual shells from people collection clams when the river tide goes out, they haul the clam in the boat and come to this little opening in the river, boil the clams to get them out of the shells and then the empty shells are thrown right there, make this huge piles.
